Take these as references, not legal advice.

The 2.2 licensing page suggests that 2.1 is *not* GPL compatible.  A
matrix of Python releases is included:

    http://www.python.org/2.2/license.html

The 2.1.1 licensing page indicates the 2.1 licensing issues are
addressed:

    http://www.python.org/2.1.1/

The FSF's free software license page indicates that versions 1.6a2 and
earlier; and 2.01, 2.1.1, and later; *are* GPL compatible.

    http://www.fsf.org/licenses/license-list.html

A note on GPL compatibility.  In general, this is taken to mean that it
is possible to mingle code licensed under a GPL-compatible license, with
GPLd code, *under the GPL*.  The GNU General Public License is
nontransitive -- you can go in but you can't go out.  This means that
using Python code in your GPLd project is acceptable, but using GPLd
code in your Python project (python code itself, not stuff written using
python), probably isn't.

Legality depends on a number of issues.  Note in general that US
copyright law consists of both civil and criminal provisions.  "Legal"
is a rather broad issue with multiple facets.

IANAL, TINLA, YADA.
